  • Magnetic recording head with high saturation magnetization write pole having alternating interface-defining Fe/Co layers
    Patent number: 6795273
    Abstract: A magnetic recording head includes a write pole having alternating layers of Fe and Co and a return pole magnetically coupled to the write pole. The layers of Fe may have a thickness from about 1.0 angstroms to about 40.0 angstroms and the layers of Co may have a thickness from about 1.0 angstroms to about 20.0 angstroms. The write pole may have a saturation magnetization greater than about 2.45 Tesla. A method for forming a write pole for a magnetic recording head is also disclosed.
